This is a bit silly question... how is polarity of T27 and T52 marked on Kef Tweeters. Is blue wire negative or positive terminal?
Are other drivers like B139, B110 etc marked with red for positive as usually.Best Regards

Unless my memory is playing trick on me again then it is the Blue wire which is the +.
Yes, on the other drivers the + is Red._________________I contend that for a nation to try to tax itself into prosperity is like a
